The main differences between brushless and brushed motors: Design: Brushless motors use electronic commutation, while brushed motors use carbon brushes and commutators. Working principle: Brushless motors control current through sensors and electronic commutation, while brushed motors change the direction of current through contact between carbon brushes and commutator. Advantages: Brushless motors offer higher efficiency, longer life, lower maintenance requirements and less electromagnetic interference.
The difference between brushless motors and brushed motors
Brushless motors and brushed motors are two different things There are significant differences in the design, operating principles and applications of motor types.

Comparison of advantages
Features | Brush motor | Brushless Motor |
---|---|---|
Efficiency | is lower (about 70-80%) | is higher (about 90-95%) |
Durability | Shorter service life | Longer service life |
Maintenance | Requires regular maintenance (replacement of carbon brushes) | Low maintenance requirements |
Noise | Lower noise | Lower noise Small |
Electromagnetic interference | Produces electromagnetic interference | Does not produce electromagnetic interference |
